The IP camera has performed the key role of monitoring and protecting user entities. But from time to time, IP cameras are used in special environments where extreme heat is present. This is where special housing is needed to protect these cameras.<\/p>\n
That was the point raised by Kintronics in a recent technology note titled “How IP Camera Enclosures are Designed for High-Temperature Applications.”<\/p>\n
Needless to say, IP cameras are tasked with the surveillance of end user entities. But there are also instances when they are needed at foundries or cement plants to monitor furnaces or other equipment where extreme heat is involved. In these circumstances, special enclosures are needed to protect the cameras against the heat.<\/p>\n
\u201cIf you need to view the inside of a blast furnace or other extreme environments such as a rocket engine test, you will need to use a specially designed camera enclosure that protects the cameras,\u201d the Kintronics note said. \u201cThis is not your normal 120\u00b0F (50\u00b0C) environment. The ambient temperature can reach over 752\u00b0F (400\u00b0C).\u201d<\/p>\n
Housing for cameras<\/strong> Further, given the environments in which the cameras are installed tend to be dirty and collect dust easily, a special mechanism is needed in the housing to clean the enclosure window. \u201cA wiper with water won\u2019t do the job in these high-temperature environments. The better enclosures include air barriers (or an air blade) that keep the front glass clean. The system uses an air compressor to reduce the maintenance required by preventing the formation of dust deposits on the glass,\u201d the note said.<\/p>\n The enclosure window<\/strong> \u201cTempered glass can be used if the temperature doesn\u2019t exceed 260\u00b0C (500\u00b0F). Quartz glass is required if the temperature reaches 400\u00b0C (752\u00b0F). Thermal cameras require different glass because they have sensors that operate at a different wavelength than optical cameras. For example, they use Zinc-Selenium glass that can be used at a temperature of up to 200\u00b0C (392\u00b0F). This glass provides transmission of 7.5-14\u03bcm wavelengths,\u201d it said. \u201cSapphire glass is used when you need to operate at up to 400\u00b0C (752\u00b0F). The glass is very clear and can pass wavelengths of .75\u03bcm to 4.5\u03bcm.\u201d<\/p>\n Cooling<\/strong> It added that the rate of flow determines the maximum operating temperature. \u201cFor example, if the flow rate is 2l\/min we can operate at up to 200\u00b0C (392\u00b0F), and the inside of the housing will be kept to a temperature of 2\u00b0C (89.6\u00b0F). If we increase the flow to 6.5l\/m, we can operate at an ambient temperature of 400\u00b0C (752\u00b0F). In this case, the internal temperature can reach 44\u00b0C (111.2\u00b0F),\u201d it said.<\/p>\n Source:<\/strong> William Pao, a&s International<\/p>\n","protected":false},"excerpt":{"rendered":" The IP camera has performed the key role of monitoring and protecting user entities.

\nAccording to the note, the enclosure, being the first level of defense in high-temperature environments, must survive the harsh environment and also provide thermal insulation that protects the camera. \u201cThey can\u2019t be plastic or standard aluminum housings because this material can\u2019t survive the extreme temperature. The housings are made from polished stainless steel. These enclosures have double chambers so that cooling air or liquid can be used to reduce the heat transfer from the ambient to the camera,\u201d it said.<\/p>\n
\nThe housing window is made from special material that not only has to survive the high temperatures, but also needs to resist thermal shock. Examples include Pyrex glass, quartz glass and tempered glass, and the glass to be used depends on the temperature of the site as well as the type of camera, according to the note.<\/p>\n
\nCooling, meanwhile, can be provided by air or water, according to the note. \u201cAir cooling will allow operation at an ambient temperature of up to 80\u00b0C (176\u00b0F). Water cooling provides the highest temperature operation. The water needs to be relatively cool. The incoming water should not be hotter than 20\u00b0C (68\u00b0F),\u201d it said.<\/p>\n
